Solve.
There are 18 boys in a class. There are w fewer boys than girls. How many students are there in the class?
g = number of girls
g - w = boys = 18
g - w = 18
g = 18 + w
boys + girls = total students
18 + (18 + w) = total students

how many fewer boys than girls are in both classes
how many fewer students voted for colored pencils than paint and crayons?
To solve this problem, we can use algebraic expressions. Let's start by assigning variables to the number of boys and girls in the class.
Let's assume the number of girls in the class is "g."
According to the given information, there are w fewer boys than girls. So the number of boys can be represented as "g - w."
We know that the total number of students in the class is the sum of the number of boys and girls. Therefore, the total number of students can be represented as: g + (g - w).
We also know that there are 18 boys in the class. So we can write the equation as:
g + (g - w) = 18
To solve for "g" and find the total number of students, we need to know the value of "w." Unfortunately, the problem does not provide the value of "w." Hence, we cannot determine the exact number of students in the class without this information.
However, if we have the value of "w," we can substitute it into the equation and solve for "g." Then, we can find the total number of students by adding the number of boys (18) to "g."
